In the drawings, which illustrate twoprelo .Figure 1 is anelevationview'of a'window and window 'frame of a vehicle body or thelike, showing oneuse of my invention;

. l Referring to the embodiment of my invention` illustrated in Figs. 1through 5 of the drawings, 4I have shown a trimming installationparticularly, thoughnot exclusively,

useful in automobile body construction. The

installation illustrated includes the body or frame part `1 which, insome instances, may

be covered with upholstery 2 (Fig. 2), the

trim strips 3 and aplurality of reversible double headed stud units 4for securing the trim strips to the frame part 1.

Trim strips or nishing strips for automobile bodywork have heretoforeusually been 4o constructed of `wood and secured to the frame part byscrews, nailsor the like. While wooden trim strips may be used inconnection with my invention, I `prefer to provide metal trim strips 3(Fig. 2), which are hollow and are pressed from single. pieces of metal.These -and can be made Thestud units .and include two substantiallysimilar socketstrips are strong, durable,.neat in appearance quickly andvery inexpensively.`

are of a novel construction engaging stud parts, each of which isprovided with a contractible and expansible head 5 and a neck 6. Thebase portion of one of the studs provides'a casing 7 which contains Ithe base 8 of the other stud member. The inf side diameter of the casing7 is larger than the diameter of the base 8 so that each `stud membershifts' relative to the other, 'for pur`A poses more fully hereinafterdescribed. j

.The body part 1 is prepared to receive the trim strip by providingtherein. a plurality of studereceiving apertures 9. Likewise the trim`strips 3 are provided with depressed portions or pockets 10 andstud-receivin apertures 1l which may be formed at the inner face of thestrip at thesame time that the strip is forme A In assembling theinstallation, the upholstery, if used, is first stretched over the framel part, and holes 12 formed therein Atofexpose the stud-receivingapertures 9 presented by the frame. The stud units may then be securedto the frame part 1 by forcing one of.

the heads 5 of each stud-unit into an aper' ture 9. Each casing 7overlies and seats.

against the upholstery to hold it in place.

the remaining unengaged heads o the studunits into the remainingstud-receivingaper tures so that the strip willbe pulled'tightly againstand yconceal-fthe edge of thel uphol-l v stery. During engagement of thestud heads -in the apertures, each stud part may shift laterallyrelative to its cooperating stud part if necessary for alignment withits coperating aperture in either the frame part 1 or the strip 3. Thepockets 10 receive the casing portions 7 of the stud-units (Figs. 2 and3) so that the inner face of the trim strip 3 may lie ciose to framepart, there being no space between except that taken up by theupholstery 2 if there be any. Thus l have rovided a trim stripinstallation which may e easily and quickly assembledand disassembled.

Referring now to Fig. 6, I have shown my invention as it appears whenthe stud unit is reversed. In this instance, the stud head that. engagedthe trim strip 3,'as shown in Fig. 2,

is shown engaging the body part 1 and the pocket 10 is formed in theframe part 1 inof in the trim strip 3. Assembly of the parts 'of theinstallation is substantially the same as described in connectionwithFigal through 5.

While I have shown and described preerred embodiments 'of my invention,it will Y '20 be understood that changes involving omispart and two studmembers secured together loosely to permit lateral shifting of kone studrelative to the -other and having a-casingportion between them, each ofsaid stud memfbers having aresilient head passing through said-apertures thereby securing the trim strip to said frame with the fabricgripped between, and said casing portion being located -in said pocket.

whereof, I have signed my In testimony name to this specication.
